Canna lily, an ornamental plant that has an aesthetic value, is very suitable for an alternative plant for a constructed wetland. This study aims to observe the ability of canna lily for phytotechnology implementation in a constructed wetland. This study is known as a range-finding test (RFT), which served as a preliminary test. Observation is conducted by preparing variation concentration of wastewater; 25%; 50%; 75%; 100% and 0% as control, which was injected into the wetland. CW (60 cm long, 60 cm wide and 60 cm deep) contained gravel medium height 25 cm with a wastewater volume 3 L. Observation measured the height of the plant, the color of the leaf, and DO, and BOD concentration. The observation was conducted for about 25 days, in term of 15 days for range finding test and 10 days for accli- mation. The results show that Canna lily could grow well, though it has some part of the withered leaf, reach height significantly, and indicated decreasing concentration of organic parameters. It is conjectured that Canna lily is very possible for a constructed wetland application.

The renewed interest in alternative onsite treatment technology by using a constructed wetland (CW). CW represents one alternative technology that may address more stringent nutrient removal standards while providing relatively low maintenance requirements and capital and operating costs. CW, a green treatment technology by simulating natural wet- lands, has been widely used to treat various kinds of wastewater such as domestic sewage, agri- cultural wastewater, industrial effluent, mine drainage, landfill leachate, stormwater, polluted river water, and urban runoff in the last few decades (Akizuki, Nagao, & Toda, 2018; Priya & Sel- van, 2017). Different types of plants can be grown in the system constructed wetland. The type of plants can be adjusted according to the type the wetland system used. Also, many plants are easy for adapting to this system. Canna lily, an ornamental plant that has an aesthetic value, is very suitable for an alternative plant for SSF constructed wetland. Canna lily has a large root system and strong enough to absorb organic matter, therefore, Canna lily can absorb more nutrients for growth and store the excess nutrient in its tissue than other aquatic plants (Yadav, Chazarenc, & Mutnuri, 2018). CWs system operating as standalone technologies are in some cases unable to meet the requirements of these new guidelines despite
